Description
In computer science, the maximum weight matching problem is the problem of finding, in a weighted graph, a matching in which the sum of weights is maximized. Here, the graph is unrestricted; i.e. can be any general graph.
Related Problems
Subproblem: Bipartite Maximum-Weight Matching
Parameters
n: number of vertices
m: number of edges
N: largest weight magnitude
